Fold Walker: An Origami‐Inspired Quadruped Robot for Multipattern Locomotion and Object Grasping

open access: yesAdvanced Robotics Research, Volume 2, Issue 1, February 2026.
This article presents Fold Walker, an origami‐inspired quadruped robot capable of multipattern locomotion and object grasping. With each leg featuring two rotational folds, the robot can transform from a flat 2D configuration into complex 3D poses. Furthermore, its trunk and legs can be one‐shot 3D printed as a unified structure, greatly simplifying ...

Dynamics of a two-dimensional upflowing mixing layer seeded with bubbles : bubble dispersion and effect of two-way coupling [PDF]

open access: yes, 2006
The evolution and structure of a spatially evolving two-dimensional mixing layer seeded with small bubbles are numerically investigated. The one-way coupling approach is first employed to show that characteristics of bubble dispersion are dominated by ...

Is There A Pure Electronic Ferroelectric?

open access: yesAdvanced Electronic Materials, Volume 12, Issue 3, 4 February 2026.
The search for faster, more reliable ferroelectric materials has shifted from traditional lattice‐driven ferroelectrics, which rely on slow ionic displacements, to electronic ferroelectrics, where polarization is governed by electronic ordering. This shift enables ultrafast switching, low‐field operation, and resistance to fatigue.

Design and Validation of SPMSM with Step-Skew Rotor for EPS System Using Cycloid Curve

open access: yesMachines
This study considers a robust design methodology to reduce cogging torque in the EPS (Electric Power Steering) of an automotive system. Cogging torque reduction is the key design factor to improve steering feeling and drive stability in an EPS system ...

Pulsed force sequences for fast phase-insensitive quantum gates in trapped ions

open access: yes, 2013
We show how to create quantum gates of arbitrary speed between trapped ions, using a laser walking wave, with complete insensitivity to drift of the optical phase, and requiring cooling only to the Lamb-Dicke regime.

Lentipes ptasan, a new species of sicydiine goby (Teleostei: Gobioidei) from the Western Pacific, with a redescription of L. mindanaoensis

open access: yesJournal of Fish Biology, Volume 108, Issue 2, Page 752-769, February 2026.
Abstract Lentipes ptasan sp. nov. is described based on specimens collected from Taiwan and Mindanao Island. It is a large‐sized Lentipes species distinguished by several male‐specific characteristics, including an upper lip protruding beyond snout obviously, fewer premaxillary tricuspid teeth, two black lines running from the front of the eye through ...

Paradoxical Topological Soliton Lattice in Anisotropic Frustrated Chiral Magnets

open access: yesAdvanced Science, Volume 13, Issue 5, 27 January 2026.
The article describes the discovery of a stable skyrmion‐antiskyrmion lattice (S‐AL) in anisotropic frustrated chiral magnets. This lattice has a net‐zero topological charge due to a balanced population of skyrmions and antiskyrmions. This is a paradoxical finding since these particles normally annihilate each other.

An Analysis of Power Friction Losses in Gear Engagement with Intermediate Rolling Elements and a Free Cage

open access: yesMathematics
Currently, mechanical gears with cycloid engagement are increasingly used in mechanisms along with involute ones. In modern drive mechanisms, using pin gears and gears with intermediate rolling elements (IRE) is widespread, which simultaneously use ...
